This invention relates to a coupler or connecter which is moreparticularly intended for connecting electric wires or conductorswit-hout soldering, although the same may be used for other analogouspurposes.

One of the4 objects of this invention is to provide a connecter of thischaracter which permits of not only properly. connecting wires ofthesame diameter but wires of widely different diameters as well withoutliability of producing an uneven strain on any of the parts whichotherwise would be liable to distort the same and impair their eiciency.t i

Another object of this invention is the provision of such a connecterwhichoperates as a lock to prevent loosenin of the nuts and bolts whichcouple the Yp ates forming' the main elements of this connecter` or fa stener and thus insure a firm and reliable connection between .therespective wires.

Further objects of the invention are to so construct the connecter thatthe same permits a connection between wires to be made in less time thanheretofore, and also to en able one man to effect such connections andthus dispense with an assistant and effect a considerable economy inthis class of work.

In the accompanying drawings: Figure 1 is aside elevation of a connecterembodying my invention and coupling two wires of different diameters.Figure 2 is a cross section taken on line 2 2, Fig. 1. Figure 3 isaperspective view of a pair of clamping plates forming part of myimproved connecter.

Similar characters `of reference indicate corresponding parts in theseveral' views.

In its general organization, the. connecter made in accordance with myimprovements comprises two clamping plates adapted to. engage opposite'sides of the wires to be cou piece of resilient sheet metal whichv isstamped or bent by suitable dies, so that the same is provided withthree longitudinal parallel corrugations 13', 14, 15. The twocorrugations 13, 15 arranged adjacent to the longitudinal edges of theplate are provided on their inner sides with longitudinally grooved jaws1.6 which are preferably AV-shaped in cross section. The centralcorrugation 14 of each plate is preferably somewhat wider than the edgecorrugation and -bulges outwardly so as to presenta convex bearing face17 on the outer side of this corrugation. p.

The tightening means preferably consists 4of two bolts which arearranged side by side lengthwise of he plates and each 'having its bodyor shank 18 passing ltransversely through corresponding openings 19formed in the central corrugations of the plates riear one end thereofand engaging the inner side ofl its head 20 with the convex bearing faceof one of the plates'while its screw nut 21 enga es itsinner side withthe convex bearing ace of the other plate. The openings 19 in the platesare enlarged in the dlrection of the width of the same, in order topermit these plates and bolts to rock the requisite extent transverselyupon each other to enable the jaws of the platesto, adapt themselves tothe surfaces of the wires to be connected.

In the operation of connecting'two wires with this connecter, the wiresare placed be tween the plates and opposite sides respectively of thetightening bolts, andthe cooperating jaws 'on the corresponding longi-ltudinal edges of the two plates are engaged with opposite sides of oneof the wires. The

bolts are now tightened so that the jaws of' insure a good electricalconnection.

As..the clamping plates ada t themselves to the surface of two wires odifferent diameter, these plates ltilt on the body of the` bolts duringwhich time the heads and nuts of the latter rock on the convexv outerbearing surface of the plates and adapt themlselves thereto, so thateach headand bolt dered less effective but also preventing thebolts'from being used over again if the occasion requires 1t. l. i

Moreover,` by providin the plates centrally with outwardly` bu gingcorrugations whichv are engaged by the heads and nuts `of the bolts,these corrugations form springs which are put under tension when thebolts yare tightened and which operate as locks revent the nuts andbolts from becommg loose` v It will be ap arent from the foregoing, thatthis device 1s ada i table to a wide ran e of wires of various iametersand that 1t may be put in use easil and expeditiously an Withoutliability o bendinglthe bolts, stripping the threads of the same, orputting any undue strain on any-of its parts.

' I claim as my'invention: Y

.A wire connecter comprising two plates each of which is bent from apiece of sheet metal to form three having'convex outer si es and concaveinner sides, the central corrugation of each plate being wider than theend corrugations on opposite sides. thereof and eachl central corrgationhaving an opening, said plates being assembled with the concave sides oftheir. vend corrugations facing each otherl and 4 adapted to engageopposite sides of the wires to be gripped, and a clamping bolt passingthrough the openings of the central corru- 'ga-tions and bearing withits head against theconvex side of the central corrugation of one plateand with its nut against the convez(A side of the central corrugationofthe other plate.l y v JOHN ZILLIOX.`
